[Freeipa-users] SLAPD stops answering

Mon Jan 9 13:06:58 UTC 2017

Hi, we have a IPA installation, which obviously needs upgrading. 
Its a single server running RHEL7.1 running IPA 4.1 

However, it have been running smooth untill now: 

Rebooting makes everything running again, but only for a few days. 

It looks like everything fails around 0:17:47 and comes up again just before 8, when the server is rebooted. 

Jan 6 00:19:46 fbbidm01 winbindd[2965]: failed to bind to server ldapi://%2fvar%2frun%2fslapd-DOMAIN.LAN.socket with dn="[Anonymous bind]" Error: Local error

Looking at the SLAPD logs also reveals it stopped answering:

It looks like it just stops answering at 00:17:48 

The slapd error log reveals nothing: 

[06/Jan/2017:00:17:34 +0100] DSRetroclPlugin - replog: an error occured while adding change number 3875312, dn = changenumber=3875312,cn=changelog: Already exists. 
[06/Jan/2017:00:17:34 +0100] retrocl-plugin - retrocl_postob: operation failure [68]

[06/Jan/2017:07:57:21 +0100] - slapd shutting down - waiting for 30 threads to terminate 
[06/Jan/2017:07:58:02 +0100] SSL Initialization - Configured SSL version range: min: TLS1.0, max: TLS1.2 

However, see a gazillion of these lines in the error log: 

DSRetroclPlugin - replog: an error occured while adding change number 3875312, dn = changenumber=3875312,cn=changelog: Already exists. 

Anyone with some thoughts about this, other that "Just upgrade".
